MDB was the firmware the device was released with.
MDL was the update that came a few weeks later.
MF3 is the current version which breaks the old root/recovery/bootloader exploits.

What did the mdl update bring to the table that makes it better than mdb?

Nothing, really. It's more of a location-based thing, and which one works better for who and where.

Actually to be more precise, it wasn't the MF3 baseband that broke root/recovery/bootloader.....it was the ROM itself that did.

I never said it was the baseband! You can flash the modem (aka baseband) for MF3 and be fine. It was actually the update to the bootloader that blew the qfuse.

The new AT&T Baseband version is I337 UCMA MF3.
Not sure about the differences above.

When it says "Baseband" that ONLY means the modem (radio) that is installed.

Now as far as being able to flash certain Roms that SAY you need to be on "MDL" baseband they are ACTUALLY referring to the FIRMWARE VERSION with THE BOOTLOADER that goes with that firmware and NOT the modem (baseband/radio) being used.
So for instance you can see MY BASEBAND above is "MDL" but my ACTUAL FIRMWARE is still on "MDB" bootloaders. So if I want to flash those Roms that say they require MDL, I would actually need to flash the BOOTLOADER that comes with the MDL firmware to be able to run those Roms. I understand where the confusion comes from on those Roms. BUT if they said you need to be on MDL BOOTLOADERS to be able to flash this ROM you would have others confused about HOW TO FLASH BOOTLOADERS and the riskyness of flashing bootloaders that CAN HAPPEN if someone doesn't understand what they are doing 100%

Upgrading baseband

I've been running MDL since I got my phone. I was using Kangabean and was having issues with my data and signal constantly going out. I upgraded to the kit kat version, but it's still doing the same thing. I feel like this is dumb to even ask, but I've searched and couldn't find anything and I'm at work so I'm sort of pressed for time right now. Can somebody suggest what baseband to use and post it? As long as it wont screw up anything from me having a first production S4 with the original exploit then I want to try upgrading. As far as I can remember, it wont have any effect. Can somebody verify this for me? Your help is greatly appreciated.

You can safely flash any modem from RockRatt's thread in the general section and see if it improves connection. The baseband will change, but not the bootloader so you'll be fine on custom recovery and such.

It isn't MDL. It was the bootloader itself which came when MDL did. Changing the baseband wont lock the bootloader.

They have the same Modem I posted for the newest there now as well. Not sure if they have all the modems for the ATT i337 though. You can find all the ATT modems in my thread in general. Just flash any/all of them and find which works best for you. These will NOT update or change your boot loader in any way.

The Original boot loader that came with the phone is MDB, but if you took the MDL update (still does not have the super locked down boot loader) then you probably have the MDL bootloaders. Either way if you have the bootloaders from MDB or MDL the original exploit will work still so MAKE SURE to keep the bootloaders you have (I still have the MDB bootloaders as well).
Also you can always check which bootloader you have by installing Terminal Emulator, open the app, type su, then type getprop ro.bootloader and it will tell you which you have.

Flashing the Modems in cwm or twrp will NOT effect the bootloaders.

Help please

I am still a bit new to flashing on the AT&T Samsung GS4 and I want to make sure I don't brick my phone. I was wondering how do I find out what version of a ROM I should flash. I am currently using GOLDENEYE 21 and I was hoping to flash GOLDENEYE 23R1 FULL ROM. I know I am still on LOKI but I don't know how to tell if it is the old or new version or if I am NF3 or NB1. My current baseband is 1337UCUAMDL. I was hoping to flash GOLDENEYE 23R1 FULL ROM.
1) My question is if I am on the older LOKI will I brick my phone by flashing this or will I be ok?
2) Do I need to upgrade to the newer LOKI?
a) If yes is there a tutorial I missed and need to read?
Thanks in advanced for any help.

Because I am latest firmware I can't help you fully. But you stated your firmware is still MDL. The baseband is the firmware. It would seem to be you should be golden with whatever you did to flash the first goldeneye.

Typically, the baseband and firmware have the same version. You would see a difference if you flash "modem". Baseband version is actually the version of the modem.

All that being said...would it be in my best interest to go ahead and upgrade my modem to a more current version or is it better to stay where I am at?

This isn't JUST directed at the OP but it could help.
The Baseband as stated is what it is reading from the modem. So Yes you can flash whichever modem you want to try in twrp,cwm, or even safestrap.
You say you are on MDL bootloader. If so this is GREAT and you can flash ANYTHING you want. IF it is a 9505 based ROM you will most likely need to flash Loki to get it to boot.
So in the actual scheme of things it is NOT the baseband that prevents users from flashing Roms and such. It IS THE BOITLOADER version.
So as long as your still on MDL or MDB bootloader, your golden.
To double check WHICH bootloader your phone is on you will need an app called "Terminal Emulator".
Open Terminal Emulator and type "su" (without the quotation marks).
Give Terminal Emulator Root Rights.
Next hit the "x" button and close terminal emulator.
Open the app again and type su enter
getprop ro.bootloader
Look at the first line and it gives the exact bootloader installed on your phone

Hope this helps others figure out and double check things before flashing. As far as OP you should be good with flashing any or the modems in recovery. Find one that works BEST for your phone and in your area. You can always flash back to your original modem as well. Just was trying to clarify things here and help you understand what is going on and why a bit. The point of flashing modems mostly will effect your download/upload speeds and sometimes a better signal. These things can vary by region. So you may fond a modem that works better or worse. It is NEVER necessary to flash modems.
It also cant hurt, because you can flash back to your original. You MAY find an OLDER modem perform better than newer as well. So test them out and see for yourself. Good luck and Happy Flashing

Need help rooting STOCK Verizon 6.0.1

Hi everyone,
I recently updated my phone about a week ago to the latest Verizon update.
I am now running Android 6.0.1 with Baseband G900VVRU2DPF4.
I'd like to ROOT my phone and run a custom debloated ROM but I'm not sure where to start as the guides have me somewhat confused.
I started with THIS link but it clearly states at the top that I need to be rooted which I don't have on my phone, should I still use the guide?
Also many guides are written for G900VVRU2BPB1 and I'm on PF4, is this a cause for concern?
Sorry for the questions but I'm inundated with questions and guides and I'm really confused no where to start.

I was in your position a couple days ago and couldn't find a way to root, so I flashed PB1 and rooted. You can download emcc brick bug app to see if you have a 15xxx.... or 11xxx... chip. If it's 15 you can flash PB1 and root, then unlock the bootloader. From there you can either upgrade to 6.0.1 or you will have a lot more custom roms available to you since many won't work with locked bootloaders.

I am trying to help my friend root his Samsung Galaxy S5, he has the exact same specs as the OP, and we also did the eMCC Brickbug check and he does have a 15xxx..... chip.
Could you provide a link to the how-to (if one exist) on how to get him from PF4 to PB1 so we can root?
Thank you.

Odin back to PB1.

S10 Plus Snapdragon version not getting OTA updates

Hello guys, i bough my phone samsung S10 Plus with Snapdragon processor, G975U, and it is running android 10, i want to update it to android 11 but it displays my phone is up to date. OTA updates or Smart Switch doesnt work, tried many times. I live in Brazil and here its sold Exynos varian, since i dislike that version, i bought the Snapdragon USA version of S10 Plus, G975U.
The phone displays AT & T carrier when i turn it on, but its full unlocked, im using my carrier here in brazil, without problems. How can i update it safely, i am afraid getting the wrong rom or brick it. My bootloader version is showed bellow.

Thanks for your help. I will install G975UOYN5GUE3 one. Since i want to keep my apps and data i must flash HOME_CSC_*** right. Or it is not recommended and i should flash just the CSC_*** file? Im not sure

For some reason when i set odin up and the files, i get stuck on file analysis. I suspect is the home_csc that is causing it to take longer. I dont want to erase all my data. Yep waited like 10 min and the process did not start, still on file analysis. Using Odin 3.14.1

Finnaly i did it. Have switch versions, odin 3.14 worked for me. 3.14.1 did not, dont know why, but Who cares, now im running android 11 on my device

Congratulations! I don't know/care about CSC stuff, I never added it to the installation list.

I flashed with home_csc so i could keep all my data and apps. Everything went fine. Thanks

Hi... how about the latest android12 firmware ? Mine is same as OP, an unlocked ATT. Is it better to flash U1 version ? Can also direct to beginner guide as i'm not familiar with these procedures..

U1 is the unlocked variant. You can crossflash any USA Samsung variant, and you will not have any issues - just the carrier bloat and services are slightly different. Keep in mind that inserting a SIM card could change your firmware.
